WHAT'S POLYPROOPYLENE RANDOM COPOLYMER (PP-R)?  

PP-R material, which is created by the new polymerization process, taking into account the heat resistance of PP-H and the low-temperature impact properties of PP-B, is suitable for the manufacture of hot and cold water supply pipeline system inside the building. 

ADVANTAGES OF USING VASEN PP-R PIPE

1. Light weight: The density of the pipe is only 0.895-0.915g/cm 3, which is only 1/9 of steel pipe and 1/10 of copper pipe. It makes handling and installation more convenient.
2. Good heat and pressure resistance: Its short-term operating temperature can up to 95 ℃. And under the temperature of 80 ℃, it still can bear some pressure for a long term. That’s the best choice for cold and hot water supply pipeline in buildings. 
3. Long service life: Under proper temperature and pressure, its service life can reach over 50 years. Good corrosion resistance: VASEN PP-R pipes have excellent corrosion resistance to most inorganic ion and common chemical substances in buildings. It is anti-corrosion and does not rust in long term use. 
4. Reliable and convenient connection: PP-R material has excellent melting welding performance. The pipes and fittings are made from the same material, joined together by melting welding. Compared to single pipe, the tensile, bending and impact strength in joint are much higher, which prevents the danger of leakage, and this kind of connection method also makes the site installation reliable and convenient.
5. Nonpoisonous and harmless: PP-R belongs to polyolefin, which is a kind of thermoplastics, whose molecule is only composed of carbon and hydrogen. And the sanitary property of the materials for VASEN PP-R pipes and fittings has been certificated by national authority organization. 
6. Good thermal and sound insulation property: The thermal conductivity coefficient of PP-R is 0.23w/m ℃, which is only 1/200 of steel pipe (43-52w/m ℃). No need to use insulating materials when used in hot water systems, which saves insulation materials and energy. And it has lower noise when water delivery in pipeline system. 
7. Better water passing capacity: The smooth inner surface of PP-R pipes and fittings have lower friction, which ensure fast running of the water. 
8. Environment-friendly building material: During production, installation and application, no pollution will be caused to the environment. Meanwhile, the materials are recyclable, which can minimize resource wasting.
